I am using Nikon D3200, I am trying to shoot a dark scene. The scene is so dark and there is minimal amount of light. I am shooting in manual mode and these are my settings. ISO 200, f/5.2, Shutter Speed 1/100.
With all these settings i am getting so much noise in the scene. Kindly tell me how to avoid noise in the Dark Scene.
Try opening the aperture of your lens as wide as it can go. The lower the f stop number, the wider the aperture. f/2.8 is wider than f/5.2 and so on. Also try reducing your shutter speed to 1/50. 1/48 is the norm for cinema, but 1/50 is as close as your camera can get.
Bear in mind that opening the aperture will cause a shallower depth of field, but this can be a good thing if you can control the focus. Not all lenses can open wide enough to eliminate noise in low light situations. I have a Nikkor 50mm f/1.8D lens and it is very good for low light at f/1.8. It won't auto focus on a D3200 though, so you would need to do that manually. It takes some getting used to. At f/1.8 you would be leaving a lot more light get through to the sensor and could therefore try lowering your ISO to 100 which would reduce the noise even further.
